I doubt in a blind test with V2 and White no.2 hardened and tempered the same anyone could tell the difference. Variations on heat treatment and glade geometry would be the major differences knife to knife. V2 compared to HD steel in edge holding is easy, HD wins. HD wins because it is so much more corrosion resistant and has much greater chromium carbide volume. Now I'm no steel expert, but the addition of Chromium .30-.50% in V2 is mainly to ensure deeper hardening.

i imagine you'd notice rather quickly on a tomato cutting test, blinded, as the white steel knives i own definitely feel the affects of acidic food quicker than the V2 knives i've used.

At .30-.50% the corrosion resistance between the two steels would be pretty much identical because there wouldn't be enough free chromium in the V2 steel to provide any corrosion resistance

Where are the steel experts?
I'm done hijacking this thread.

there are many small composition issues in the two steels, beyond the small chromium difference. i'm just going by experience with knives of the two steels, here. it's somewhat subjective, obviously, but a knife either keeps cutting or it doesn't. when cutting a lot of tomatoes, something i do fairly regularly, my white steel knives start struggling on tough skins before my V2 knives do. it's part of why i don't have white 2 gyutos, anymore. i don't have the issue with Blue 2 and Blue AS knives, either.
